TRTL Bot (http://www.trtlbot.com) has announced the Minimalist 4, an “eco-functional” case for the iPhone 4 that is only being offered during the holiday season. It combines the protection of a case and the capability of a money holder, allowing you to carry up to three ID/credit cards with your phone.

Designed and manufactured in the Los Angeles area using recycled plastic, the white Minimalist 4 is similar to its predecessor, the Minimalist 4 and TRTL Stand 4, containing at least one plastic water bottle per case. TRTL Bot blends minimalistic design with simple practicality, both represented in the white color of the case, says President Peter Gloria.

Both the white and black Minimalist 4 and the TRTL Stand 4 are currently available for US$34.99 at the TRTL Bot web site.  For iPhone 3G/3GS users, a Minimalist 3G/3GS is also available in black or white for $24.99.
